Osedax mucofloris, only the third Osedax species described and the first Osedax known from the Atlantic Ocean, was described by Glover et. al (2005) from an experimentally deposited carcass of a Minke Whale (Balaenoptera acutorostrata) at a depth of 125 meters in the North Sea. This species has also been collected in the North Sea from submerged Pilot Whale (Globicephala melas) bones at a depth of 30 meters and Minke Whale (Balaenoptera acutorostrata) bones at a depth of 125 meters (Dahlgren et al. 2006). Osedax worms were previously known only from deep-sea (1500 to 3000 meter) whale-falls in the northeast Pacific. Glover et al. discuss the implications of such a global distribution of the genus Osedax for understanding the phylogeography, historical biogeography, and diversification of this group.
